Well, I'm not saying the school is bad but if they only have one guy for CPL or even if they continue employing this guy despite being such a lousy instructor, they're complicit in one way or another. As Duchess says, it's normal for people to not like each other but in a business relationship such as this, you really shouldn't be giving him/them your business as not only is it an unpleasant experience for you, I would wager to say that this friction is hurting your learning which is essentially the "product" they are selling to you. You won't pay full price for a sub-standard product now, would you?
